Add Quartz-based MessagingTaskScheduler [INT-103]

[spring-operator]

Mark Fisher opened INT-103 and commented

Currently, the only MessagingTaskScheduler implementation is the SimpleMessagingTaskScheduler. It only supports the interval-based PollingSchedule. A Quartz-based version of MessageTaskScheduler should be added to support a cron-based implementation of the Schedule interface.

Moving to M5.

The new approach for sending poll-command triggers to endpoints (in M5) should provide the foundation for this (as well as WorkManager delegation).

Resolved by introducing the Scheduling SPI and the QuartzSchedulerServiceProvider.

Integration would be provided by using the following configuration:

<message-bus task-scheduler="quartzTaskScheduler"/>

followed by

<beans:bean id="quartzTaskScheduler" class="org.springframework.integration.scheduling.spi.ProviderTaskScheduler">
beans:constructor-arg
<beans:bean class="org.springframework.integration.quartz.QuartzScheduleServiceProvider">
beans:constructor-arg
<beans:bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"/>
</beans:constructor-arg>
</beans:bean>
</beans:constructor-arg>
</beans:bean>

essentially injecting fully configured Quartz factory bean in the message to be wrapped as a TaskScheduler.

The SchedulerFactoryBean can be configured using all features provided by the core Spring-Quartz integration.
